Abstract: This disclosure relates to automatic text analysis. A source device comprises an input port to receive text data representing text that comprises multiple text segments. A text processor transforms the text data to numeric values that represent the multiple text segments. An encryption engine encrypts the numeric values into encrypted numeric values. An aggregation device aggregates the encrypted numeric values into aggregated encrypted numeric. Finally, a learning device remote from the source device provides an analysis of the text data by performing a learning method on the aggregated encrypted numeric values using operations that maintain the aggregated encrypted numeric values and thereby the text data concealed from the learning device. The numeric data values allow encryption to preserve privacy while, at the same time, allowing learning on the numeric data on a remote device without disclosing the text data because the aggregated numeric values remain concealed from the learning device.
